Subject Cassandra - conflict resolution for column updates with identical timestamp
Date Sat, 23 Mar 2013 16:12:56 GMT

I would like to know which write wins in case of two updates with the
same client timestamp in Cassandra.

Initial data: KeyA: { col1:"val AA", col2:"val BB", col3:"val CC"}

Client 1 sends update: KeyA: { col1:"val C1", col2:"val B1"} on Sx

Client 2 sends update: KeyA: { col1:"val C2", col2:"val B2"} on Sy

Both updates have the same timestamp.
